IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 125,988, dated April 23, 1872.

Specification describing a new and useful Improvement in Breech-Loading Fire-Arms, invented by ()RYILL M. ROBINSON, of Plattsburg, in the county of Clinton and State of New York.

Figure 1 represents section of my invention. view of the operating parts. tional elevation of carrier.

Similar letters of reference indicate corresponding parts.

The invention will first be fully described in connection with all that is necessary to a full understanding thereof, and then clearly pointed out in the claims.

I A in the drawing represents the receiver of the fire-arm; B, the barrel of same. The barrel is inserted within the front part of the receiver and secured therein by means of a pin, a, which is conical, and serves to adjust the barrel with exactness to its position. 0 is the sliding breech and cartridge-extractor, made to slide within the receiver A, and connected at its rear end, by a link, b, with the breechbloek D, which is pivoted at its back end, as shown. E is the carrier-block, fitted into the breech to slide up and down, and provided with recesses e e 0 A pivoted lever, F, which extends back to near the hammer G, enters with its front end a notch in the carrier-block.

When the breech-block D is at the point of highest elevation it'strikes the rear end of the lever F, and thereby causes the elevation of the carrier-block and the consequent ejection a longitudinal vertical Fig. 2 is a detail side Fig. 3 is a secof any empty cartridge-shell that may have been withdrawn from the barrel by the ore tractor C during its backward motion. At the same time, if on a magazine-rifle, the block E elevates from the magazine H a full cartridge intoline with the barrel. Vhen the breechblock is next swung down the sliding breechblock pushes the new cartridge home into the barrel. The carrier then descends in line with the magazine to receive a new cartridge. The

descent of the carrier is efi'ected by the lever F when struck by a projecting pin, 0, of the breech-block.

\Vhen the rifle is not a magazine-rifle it will not be necessary to swing the breech-block so far back as to raise the carrier, as the new cartridge can be introduced by hand from above.

The discharge of the empty cartridge-shell may as well be carried out at the side as on top, in-case an appropriate opening is made in the side of the breech.

The breech-brace D has a projecting tongue, (I, at the rear end, under which the hammer fits when firing, as in Fig. 2. The hammer thereby locks all parts when firing. I is a pin projeetin g from the trigger-guard strap J for the purpose of serving as a stop for the cartridge from the magazine to rest against.

As it may be necessary to use cartridges of greater or less length this stop I is made adjustable on the strap, so that it can be set more or less forward or back to accommodate cartridges of suitable length. For this purpose the pin is sustained by a thumb-screw, e, which presses through a slot in the triggerguard strap.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A lever, F, and breech-block brace D d, combined with the notched carrier E, to raise it at the times and in the manner set forth.

2. The stud 0, arranged on the breech-block brace D, in combination with lever F, for the purpose of depressing the latter, as set forth. 3. An adjustable stop, I, and slotted triggerguard strap J, combined, as described, with the notched carrier E, to admit of diti'erent lengths of cartridge.
